4. Track your sleep and determine how much sleep is optimal for you. Use any of the tracking devices (such as fitbit) or Apps (such as sleep time) to correlate how you feel in a following day and how many hours you slept on the preceding night. People vary in their need for sleep, from as few as three or four hours a night to as many as 10. Most require seven to eight hours, but ideal amounts can change over time, and may vary from day to day. Say, after a day at the Gym, you would need an extra few hours. You can adjust your bedtime and see how you feel after sleeping for various amounts of time, or simply note how much you slept on days when you feel rested and productive.

If you do wake early, try to use the time productively. Read or write for an hour, then try to go back to sleep until morning.
